Above is typically what you need if you pour on a 1 block a day production schedule. Slowly add water to 1 part concrete powder, 3 parts sand while mixing until you have a "pancake batter" type mix. Give the mold a few shakes to confirm the concrete is settled. Wait 24 hours to remove the mold. Add fresh release agent to the form and re-assemble, ready for the next pour.

Mass Block Production

For the really serious block pourer!

To the left is what the more serious block pourer uses. 1 part concrete to 5 parts navi jack, or with leftovers at the redi-mix plant. Notice in the picture that the forms are clamped in the pouring station eliminating the need for straps. In the picture to the right you can also see the electric motor on the bottom that vibrates the forms.
